Pharrell Williams has penned the world’s most convoluted self-help book.

The first four pages of the tome, entitled Inspiration, have been published online and, inexplicably, readers are asked to fill in the missing word blanks to guess what the musician and producer might be saying.

The first fan to guess the correct word wins themselves a credit in what will surely be a best-seller. Weirdly, the project has been created in association with Tipp-Ex and Bic.

So, essentially, you can only learn from the wisdom of the Happy singer if you have the time or inclination to guess what he’s saying. The book will only be published online in its entirety when all the missing words have been found.

To first few pages focus on Williams’s musical knowledge, and – to pay him his dues – he does have extensive experience in the industry, having worked with everyone from Justin Timberlake and Mile Rodgers to Daft Punk and Mile Cyrus. Everything he touches does seem to turn to gold, yet the reason for making his new project so inaccessible is difficult to phantom.

Revenue from the book will go to Williams's non-profit organisation From One Hand to Another that aims to help young people at risk. This is, in fact, his second book, having released Places and Spaces I've Been in 2012.
